Mercedes-Benz powertrain plants: Production launch for key components of the series-produced battery-powered eActros
Comunicato Stampa disponibile solo in lingua originale.
- The first #components have been produced for the upcoming series production of the battery-powered #eactros. The electric truck will start rolling off the assembly line in Wörth am Rhein on 7 October 2021.
- The #mercedesbenz plant in Mannheim has begun to assemble the battery packs, while the #mercedesbenz plant in Kassel has commenced assembling the electric axles and the
Mercedes-Benz plant in Gaggenau is manufacturing the associated transmission #components. - Yaris Pürsün, Head of Global Powertrain Operations Daimler Truck: “The launch of component production for the first series-produced all-electric truck bearing the Mercedes star is of great significance for us. Because of our battery packs, electric axle and drive system #components, we are extensively involved in making the #eactros a vehicle of #mercedesbenz quality that will be locally carbon neutral out on the road.“
Gaggenau/Mannheim/Kassel — The #mercedesbenz powertrain plants in Germany are starting production of key #components for the battery-powered #eactros. They include the electric axle and the battery packs, which are produced and assembled at the plants in Gaggenau, Kassel and Mannheim. These #components will be used for the series production of the #eactros, which will begin at the #mercedesbenz plant in Wörth on 7 October 2021.
Yaris Pürsün, Head of Global Powertrain Operations Daimler Truck: “The launch of component production for the first series-produced all-electric truck bearing the Mercedes star is of great significance for us. Because of our battery packs, electric axle and drive system #components, we are extensively involved in making the #eactros a vehicle of #mercedesbenz quality that will be locally carbon neutral out on the road. Our first series-produced all-electric truck from #mercedesbenz thus has impressive inner values because key #components are produced at our German locations in accordance with top quality standards. This is ushering in a new era for the production and technology network of our German powertrain plants.”
Battery packs from the #mercedesbenz plant in Mannheim
The Competence Centre for Emission-free Mobility (KEM) in Mannheim assembles individual battery modules into complete packs, which it then subjects to a function test. A battery pack for a series-produced #eactros consists of six individual battery modules. A completely assembled pack is almost 2.20 metres long, 75 cm wide and 55 cm high. But before the modules become part of an operational pack, they are first installed into a metal housing and then connected to other #components such as busbars, control systems and wires. They are then wired to the high-voltage cable sets, after which insulation layers that meet the highest safety standards are applied. In the final step, the electric/electronic box (E/E box) is attached to the pre-assembled metal housing, which will later form the interface between the battery and the vehicle. The E/E box is also pre-assembled at the #mercedesbenz plant in Mannheim. After a final function and leakage test of the entire battery pack, the component is shipped to the #mercedesbenz plant in Wörth.
The electric axle: A major role for the #mercedesbenz plant in Kassel
The #mercedesbenz plant in Kassel assembles the complete electric axle, consisting of the axle bridge, the electric motor and the shiftable transmission elements. The core axle is pre-assembled first. Among other things, this involves attaching the wheel hubs and the brake disks to the axle bridge. The drive unit, including the two-speed transmission, is pre-assembled in parallel. The #mercedesbenz plant in Gaggenau supplies the transmission #components for this step. After the core axle is pre-assembled, the entire drive unit, including the two-stage transmission, is “married” (attached) to the axle. Before the electric axle is prepared for shipment, it is subjected to a function and high-voltage test. These tests especially examine electrical safety and noise properties.
The electric axle is mounted on the same basis as its conventional counterpart. As a result, it is possible to integrate the manufacturing and assembly processes of the electric axle into existing production lines in parallel with the conventional production series. This makes the production process extremely flexible and cost efficient. During the integration of the electric axle, the main focus was on the commissioning of machines that were either adapted to the production of electric axles or newly purchased for them. This equipment includes machines for the pre-assembly of the drive unit, the final assembly of the electric axle and the entire test procedure.
